Looking forward to receiving this device and installing GCam on it. I'll be sure to post impressions/comparisons. From the reviews on YouTube, it seems the rear cameras are capable, but not so good in lower light. And the front facing selfie camera is pretty poor. It tends to overexpose faces and completely blow out backgrounds. Hopefully TCL addresses this with a software update.
Edit: Although I ordered early Tuesday morning, retarded Amazon didn't ship until today (Thursday) and estimated delivery is now Saturday. Ugh. Hopefully it doesn't get lost or stolen in transit. They used their crappy lasership service. I don't have high hopes.
